Pine Trees

I have a crazy question. I am doing a deer hunters theme cake and want to put pine trees. I have seen the upside down cone on a pretzel stick. I like how it looks. My question is do you just balance the cone on the stick or is the cone filled with something to make the pretzel sturdy? Thanks for the help!

I think that they might be filled with fondant and then the pretzel is stuck in or maybe even rkt. I don't make my trees that way. I roll a piece of green fondant into a cone and then use a pair of sharp curved but pointed scissors to cut the limbs. This is a tutorial that I used:
